Is the expectation then to have security functions also decrease size

1-2% performance hit on systems which have become at least several
hundred % faster over recent years is not a significant performance
regression compared to the baseline before.

Where do you get these fantastic numbers? Where can I buy a system like
that? Commonly we see regressions with single threaded integer
performance on most newer processor generations.

These hundreds of percent improvement can only come from floating point
performance using specialized instructions. There are only a very limited
number of applications that can make use of it.
